GS-00001 : Failed to allocate 4592381952 bytes for sga

GS-00001 : Failed to allocate 4592381952 bytes for sga

• 在安装GaussDB 100，执行python install时发现如下错误：

Error: Can not get instance '/opt/gaussdb/data' process pid,The detailed information: 'instance startup failed '
查看zengine.rlog发现为GS-00001: Failed to allocate 4592381952 bytes for sga

• 此错误为安装时没有指定数据库内存分配大小导致，因为安装环境为测试环境，而安装默认是4G大小，所以导致报错

python install.py -U omm:dbgrp -R /gdb/gaussdb/app -D /gdb/gaussdb/data -C LSNR_ADDR=127.0.0.1,192.168.79.137 -C LSNR_PORT=1888 -C DATA_BUFFER_SIZE=200M -C SHARED_POOL_SIZE=100M -C TEMP_BUFFER_SIZE=100M

-C SHARED_POOL_SIZE=100M
-C DATA_BUFFER_SIZE=200M
-C TEMP_BUFFER_SIZE=100M

• 修改之后查看安装，顺利完成
